RECOMMENDED PREMEDICATIONS1

Administer premedications 30 minutes to 2 hours prior to starting MONJUVI infusion to minimize IRRs. Premedications may include acetaminophen, histamine H1 receptor antagonists, histamine H2 receptor antagonists, and/or glucocorticosteroids.

For patients not experiencing IRRs during the first 3 infusions, premedication is optional for subsequent infusions.

If a patient experiences an IRR, administer premedications before each subsequent infusion.

IRR=infusion-related reaction.


DOSAGE MODIFICATIONS FOR ADVERSE REACTIONS1

Management guidelines for IRRs and myelosuppression

Infusion-related reactions (IRRs)  
Severity Dosage Modification
GRADE 2
(moderate)

  • Interrupt infusion immediately and manage signs and symptoms

  • Once signs and symptoms resolve or reduce to grade 1, resume infusion at no more than 50% of the rate at which the reaction occurred. If the patient does not experience further reaction within 1 hour and vital signs are stable, the infusion rate may be increased every 30 minutes as tolerated to the rate at which the reaction occurred
GRADE 3
(severe)

  • Interrupt infusion immediately and manage signs and symptoms

  • Once signs and symptoms resolve or reduce to grade 1, resume infusion at no more than 25% of the rate at which the reaction occurred. If the patient does not experience further reaction within 1 hour and vital signs are stable, the infusion rate may be increased every 30 minutes as tolerated to a maximum of 50% of the rate at which the reaction occurred

  • If after rechallenge the reaction returns, stop the infusion immediately
GRADE 4
(life-threatening)

  • Stop the infusion immediately and permanently discontinue MONJUVI
Myelosuppression  
Severity Dosage Modification
Platelet count of
50,000/mcL or less

  • Withhold MONJUVI and lenalidomide and monitor CBC weekly until platelet count is 50,000/mcL or higher

  • Resume MONJUVI at the same dose and lenalidomide at a reduced dose. Refer to lenalidomide prescribing information for dosage modifications
Neutrophil count of 1,000/mcL or less for at least 7 days

OR

Neutrophil count of 1,000/mcL or less with an increase of body temperature to 100.4 °F (38 °C) or higher

OR

Neutrophil count less than 500/mcL

  • Withhold MONJUVI and lenalidomide and monitor CBC weekly until neutrophil count is 1,000/mcL or higher

  • Resume MONJUVI at the same dose and lenalidomide at a reduced dose. Refer to the lenalidomide prescribing information for dosage modifications

CBC=complete blood count.

Refer to the lenalidomide prescribing information for lenalidomide dosage recommendations.
